Methods and Arrangements in a Telecommunication Network

Abstract

The present invention relates to methods and arrangements for automatically providing presence status information regarding the line state in the IMS. This is achieved by a client based solution. The client ( 100 ) receives line state information from the voice/video module ( 220 ) of the user terminal and transfers the received line status information to the IMS module ( 230 ) of the user terminal. The IMS module ( 230 ) publishes the line status information to e.g. the PGM of the IMS ( 30 ) such that the line status information can be notified as presence information in the IMS.

         13 . A user terminal client configured for wireless communication with a mobile telecommunication network that includes an Internet Protocol Multimedia Subsystem, IMS, wherein the client comprises:
 a voice/video module configured to manage connections to a voice/video switching network of the mobile telecommunication network;   an IMS module configured to manage IMS connections; and   a control unit comprising a receiver configured to receive line state information from the voice/video module and a transmitter configured to transmit the received line state information to the IMS module;   wherein the IMS module comprises a transmitter configured to publish the line state information to a node of the IMS such that the line state information can be notified as presence information in the IMS.   
     
     
         14 . The user terminal client according to  claim 13 , wherein the control unit is adapted to configure the voice/video module to transmit the line state information to the receiver of the control unit upon request, wherein the control unit further comprises a second transmitter configured to request the line state information from the voice/video module, and wherein the receiver of the control unit is configured to receive the line state information responsive to the second transmitter sending said request to the voice/video module. 
     
     
         15 . The user terminal client according to  claim 13 , wherein the control unit is adapted to configure the voice/video module to transmit the line state information to the receiver of the control unit when a voice/video call is established and wherein the voice/video module includes a transmitter configured to send the line state information to the receiver of the control unit when the voice/video call is established. 
     
     
         16 . A control unit for a user terminal client configured for wireless communication with a mobile telecommunication network that includes an Internet Protocol Multimedia Subsystem, IMS, wherein the control unit comprises:
 a receiver configured to receive line state information from a voice/video module of the user terminal client that manages connections to a voice/video switching network of the mobile telecommunication network; and   a transmitter configured to transmit the received line state information to an IMS module of the user terminal client that manages IMS connections, such that the line state information can be published in the IMS to be notified as presence information.   
     
     
         17 . The control unit according to  claim 16 , wherein the control unit is adapted to configure the voice/video module to transmit the line state information to the receiver upon request, wherein the control unit further comprises a second transmitter configured to request the line state information from the voice/video module, and wherein the receiver is configured to receive the line state information responsive to the second transmitter sending said request to the voice/video module. 
     
     
         18 . The control unit according to  claim 16 , wherein the control unit is adapted to configure the voice/video module to transmit the line state information to the receiver when a voice/video call is established. 
     
     
         19 . A method in a user terminal client configured for wireless communication with a mobile telecommunication network that includes an Internet Protocol Multimedia Subsystem, IMS, wherein the method comprises:
 receiving line state information at a control unit of the user terminal client from a voice/video module of the user terminal client that manages connections to a voice/video switching network of the mobile telecommunication network;   transmitting the received line state information from the control unit to an IMS module of the user terminal client that manages IMS connections; and   from the IMS module, publishing the line state information to a node of the IMS such that the line state information can be notified as presence information in the IMS.   
     
     
         20 . The method according to  claim 19 , wherein the method further comprises:
 configuring, by the control unit, the voice/video module to transmit line state information upon request;   sending a request for line state information from the control unit to the voice/video module; and   receiving the line state information at the control unit responsive to the control unit sending said request to the voice/video module.   
     
     
         21 . The method according to  claim 19 , wherein the method further comprises:
 configuring, by the control unit, the voice/video module to transmit line state information when a voice/video call is established; and   sending line state information from the voice/video module when the voice/video call is established.   
     
     
         22 . A method in a control unit for a user terminal client configured for wireless communication with a mobile telecommunication network that includes an Internet Protocol Multimedia Subsystem, IMS, wherein the method comprises:
 receiving line state information at a control unit of the user terminal client from a voice/video module of the user terminal client that manages connections to a voice/video switching network of the mobile telecommunication network;   transmitting the received line state information from the control unit to an IMS module of the user terminal client that manages IMS connections, such that the line state information can be published in the IMS to be notified as presence information.   
     
     
         23 . The method according to  claim 22 , wherein said receiving comprises:
 configuring the voice/video module to transmit line state information upon request;   sending a request for line state information from the control unit to the voice/video module; and   receiving the line state information at the control unit responsive to the control unit sending said request to the voice/video module.   
     
     
         24 . The method according to  claim 22 , further comprising configuring the voice/video module to transmit the line state information to the control unit when a voice/video call is established.
